DEMOUNTABLE-VEHICLE-RIM FOB RESILENT TIRES.

Specification of Letters Patent;

Patented Jan. 1&1, 1911.

Application filed March 1'?, 1910. Serial No. 549,927.

To all whom it may concern:

.car or other vehicle wheels.

The object or" the invention is to provide an improved Construction of demountable resilient tire seating riis for motor car or other vehicle wheels, unich will be strong, simple and durable, enable the tire and its seating rim to be quickly removed and replaced when required, and which at the same time will exert no outward or bursting pressure upon the tire seating' rim.

'Our invention consists in the means we employ to practically accomplish this object 01' result, as herein shown and described. 25'

In the accompanying drawing forming a part of this specification, Figure l is a side elevation of a resilient tired motor car or other vehicle wheel having a. demountable rim embodying our invention. Fig. 2 is an enlarged, partial cross section on line 2-2 of Fig. 1. ,Fig 3 is a partial vertical section on line 3 3 of Fig. 2.

In the drawing, 1 represents a motor car or other vehicle wheel, Q a resilient, preferably pneumatic, tire therefor, 3 the tire seating rim, l the telly of the wheel, 5 a metal band. shrunk thereon in the usual manner and having at thc inner side of the 'wheel a liiangetl furnished with an internal and outwardly projecting cone or annular wedge face 7.

8 is a ring member, preferably in a separate piece from the tire seating rim and having at the inner side of the wheel a cone face 9 adapted to interengage with the cone face 7 of. the flange G, and on the outer side ot' the wheel a cone lace 1 0 adapted to en-l with the. corresponding cone .tace 11 of the separate piece clamp ring 12. The clamp ringl 12 is also provided with ay beveled wedging or cone face 13, adapted to engage with the corresponding wedging or cone tace 14 of the metal band 5. rlhe ring 8, if it is made in a separate piece from the tire seating rim 3, is preferably secured thereto by rivets 15.

16 are clamp bolts extendinv preferably through the flange of the zb hrough the clamp ring 12, the saine being furnished -with 'a threaded nut 17 and washer 18.

By simply unscrewing the nuts 17, the tire and its seating rim 3 and attached ring 8 may be readily and very quickly removed and replaced with another. As the nuts 17 of the clamp bolt 16 are screwed home, the opposing-cone or annular wedge faces-7, 11 on the band 5 and clamp ring 12 embrace 'and tend to draw inwardly between them the ring 8 of the tire seating rim 3, and thus, while very firmly and securely clamping and and 5 and,

binding the parts together, exerting no out.-

ward or bursting strain whatever upon said tire seating rim 3 or its ring 8.

The wheel, resilient tire and the tire seating rim 3 may allbe of any suitable, vdesired or known construction. By simply riveting the cone or annular wedge faced ring 8'onto a tire seating rim oi' any known construcl tion, and applying' to the fellyot the wheel the metal band 5 with its flange G and cone or annular wedge face 7, the tire seating rim is made demountable through the agency of the clamp ring 12, the cone or annular wedge face 11 of which engages on the outer side the ring 8.

As illustrated in the drawing, the tire seating rim 8 is of a well known, quick, den tachable side ring type, that is to say, provided on the inner side of the wheel with a flange 18 and side ring 19, and onthe outer side of the wheel with a groove 20, detachable' split ring 21 and side ring QQ.

The ring 8 on the tire seating rim 3 is provided with notches or eut out portions Q3 at the clamping bolt 16 to accommodate same and permit all the parts to be properly seated or forced home without interference from the clamp bolts. c

ln our invention, dirt is entirely excluded from between the tire seating rim and the metal band surrounding the folly of the wheel as the cone contacting faces or' the interengag' ig rings torni tight joints. find in our invtntion also. owing to the cone contacting 'faces ot the interengaging rings, no difficulty is or can be experienced in sepan rating the parts b v reason ot' their becoming rusted.

1. ln a deinountable.vehicle wheel rim, the coinliination with ay metal band on the wheel, having` on the inner side of the Wheel an annular flange provided with acone or annular Wedge face, of a tire seating rim 3 having on its inner face a member furnished with two cone or annular Wedge faces, and a clamp ring having a cone or annular wedge face, and means for clamping and holding together said flange and metal band and said Clamp ring, said interengaging cone or annular Wedge faces on said mem.- bers operating to inwardly draw or bind the tire seating rim and exerting Ano outward or bursting pressure thereon, substantially as specified.

'2. In a demountable vehicle Wheel rim, the combination with a metal band on the Wheel, having on the inner side of the Wheel an annular flange provided )Vith a cone 0r annular Wedge face, of a tire seating rim 3 having on its inner face a member furnished with two Cone or annular Wedge faces, and a clamp ring` having a cone o r annular Wedge face, said interengaging cone 0r annular and exerting no outward or bursting pres-l sure iereon, and clamp bolts extending` .through said clamp ring and the flange of said band, substantially as specified.

3, In a demountable vehicle Wheel rim, the vcombination with a metal band on the Wheel, having on the inner side of the Wheel an annular flange provided with a cone or annular Wedge face, of a tire seating rim 3 having' on its inner face a member furnished with two cone or annular Wedge faces, and a clamp ring having a cone or annular Wedge face, and means for blamping and holding together said flange and met-al band and said clamp ring, substantially as specilied.
